I have the exact same problem on my Dell Inspiron 6000:

[root at mobile ~]# hdparm -d1 /dev/hdc

/dev/hdc:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 using_dma    =  0 (off)

This stinks, I can't watch DVDs on my laptop.

Here's my info...

[root at mobile ~]# cat /proc/ide/hdc/model
SAMSUNG CDRW/DVD SN-324S
[root at mobile ~]# cat /proc/ide/hdc/driver
ide-cdrom version 4.61
[root at mobile ~]# cat /proc/ide/hdc/settings
